01 - Whisk together sourdough discard, milk, eggs, melted butter, and vanilla extract in a large mixing bowl until smooth and fully incorporated.
02 - In a separate bowl, whisk together flour, sugar, baking powder, baking soda, and salt until evenly distributed.
03 - Pour dry ingredients into wet mixture and fold gently with a spatula until just combined. Stop mixing when a few small lumps remain—overmixing will produce tough pancakes.
04 - Heat a nonstick skillet or griddle over medium heat. Lightly grease the surface with butter or cooking oil.
05 - Pour approximately ¼ cup of batter per pancake onto the preheated skillet. Cook for 2–3 minutes until bubbles form across the surface and edges appear set.
06 - Carefully flip each pancake and cook for an additional 1–2 minutes until golden brown and cooked through the center.
07 - Repeat the cooking process with remaining batter, adding more butter or oil to the pan as needed to prevent sticking.
08 - Stack warm pancakes on serving plates. Accompany with maple syrup, fresh berries, or preferred toppings.
